Office figures: Malta publishes no open office-vacancy figure for Valletta that could be read: the National Statistics Office, the Planning Authority and the national spatial-data portal all answer automated requests with a bot challenge or HTTP 403. The radar lists 20 office, commercial and retail buildings from OpenStreetMap as the stock to look through. Homes: our economic model’s conversion engine. Map built 2026-10-09.
One point per building, from public records, open data and cited reports. Filter by type, size and how sure the evidence is; open one to see who says so and whether it could become homes.
Malta has no public register of empty, derelict or dangerous buildings that could be read: the Planning Authority's map server and website (Cloudflare challenge), the spatial-data portal msdi.data.gov.mt (HTTP 403) and the National Statistics Office (HTTP 403) were not crossed; the census vacancy figures for Valletta would be in the NSO's census volumes, which could not be read.
Check any building in Valletta: could it become homes, and could the EHC model work there?
The articles do not give an address we could place, so these have no pin yet. From news reports, summed up in our own words with a link to each article — not checked on site by EHC.
The districts where empty space, the right zoning and a working neighbourhood come together, and the owners and programmes that open a door.
The harbour-front warehouses and the old fish market are the State's own empty heritage buildings.
Risk: Already in concession or tender: the Pixkerija call asked for 65-year concessions and €18 million of investment.
Two lettable government premises on one plan, offered on lease with sealed tenders.
Risk: Small premises of unstated size; not a whole building.
The Evans Building, the city's largest disused public building in the news, sits on the way to Fort St Elmo.
Risk: The concession is settled in court; a co-operative would have to ask the Lands Authority and the government what remains open.
Decisions, auctions and closures that change what becomes available, and when.
The Court of Appeal overturned two review-board decisions of March and restored Valletta Luxury Projects as winner of the 65-year concession (€78 million bid).
Current terms and application forms for rehabilitating vacant dwellings (grant up to €50,000, ten-year lease to the Authority) were uploaded in February 2026.
Malta Strategic Partnership Projects opened a call, until 30 August 2023, for a 65-year concession over the old fish-market buildings.
A government-owned company applied to demolish a derelict Valletta building and rebuild it as three social-housing units (twelve residents); the article gives no address.
